Subject: [PATCH RFC 00/11] iommu: SVA and IOPF refactoring
Date: Sun, 20 Mar 2022 14:40:19 +0800 [thread overview]
Message-ID: <20220320064030.2936936-1-baolu.lu@linux.intel.com> (raw)
Hi,
The former part of this series refactors the IOMMU SVA code by assigning
an SVA type of iommu_domain to a shared virtual address and replacing
sva_bind/unbind iommu ops with attach/detach_dev_pasid domain ops.
The latter part changes the existing I/O page fault handling framework
from only serving SVA to a generic one. Any driver or component could
handle the I/O page faults for its domain in its own way by installing
an I/O page fault handler.
This series overlaps with another series posted here [1]. For the
convenience of review, I included all relevant patches in this series.
We will solve the overlap problem later.
This series is also available on github here [2].

Please help review and suggest.
Best regards,
baolu
